GEORGE L. KNIGHTS, OF AMESBURY, MASSACHUSETTS, ASSIGNOR TO PETTINGELLMACHINE (30.; OF AMESBURY, MASSACHUSETTS, A CORPORATION OF MASSACHU-SETTS.

BEADING, MOLDING, AND CUTTING MACHINE.

To all whom it may concern:

Be it known-that I, GEORGE L. KNIGHTS, a citizen of the United States,residing at Amesbury, in thecounty of Essex and State of Massachusetts,have invented a new and useful Improvement in Beading, Molding, andCutting Machines, of which the following is a specification.

This invention is a novel construction of beading, molding, and cuttingmachine and can also be utilized as a folding machine for folding overthe edges of metal around the reinforcing wire, such as ordinarilyemployed in mud guards for automobiles and carriage metal body work.

The object of the invention is to provide an exceedingly simple andefficient machine by means of which molding and beading can be quicklyand easily formed in sheet metal and a still further object is toprovide for the accurate manipulation of the various parts.

A still further object of the invention is to provide for the quick andeasy adjustment of the various parts.

With these various objects in View, my invention consists in the novelfeatures of construction and combination of parts all of which will befully described hereinafter and pointed out in the claims.

In the drawings forming a part of this specification: Figure l is aperspective view of a machine constructed in accordance with myinvention. Fig. 2 is a front view of the same. Fig. 3 is a sectionalelevation. Fig. l is a detail view of the beading rolls. Fig. 5 is adetail perspective view showing the guide and gage used in connectionwith the machine.

In all of these figures, I have omitted the forming or beading rollsfrom the ends of the shaft for the clearness of illustration.

In carrying out my invention, I employ a cast metal frame or body Acomprising a pedestal base A and the hollow parallel arms A and withinthe hollow pedestal and arms are arranged substantially all of theworking parts of the device. A gear case B is arranged upon the rear ofthe pedestal for the purpose of containing the driving gears hereinafterreferred to. A horizontal shaft C is journaled in the lower hollow armextending through the forward end of said arm as shown at C while at therear end it extends through the pedestal and carries the Specificationof Letters Patent.

large gear D. The shaft also has a small gear D keyed thereon adjacentthe rear end but within the hollow pedestal, said gear D meshing with asimilar gear E keyed upon the upper rotary shaft E. This upper shaft Eis supported at its rear end in a hanger F pivoted within the hollowcasing as shown at F. The forward end of the shaft E is journaled in ahanger G, which hanger is supported by means of a stout laminated springH fastened at H by means of a bolt to the top portion of the casing, thetendency of said spring H being to move the hanger G and consequentlythe forward end of the shaft E upwardly and this upward movement isarrested and the position of the roll determined by means of the handwheel and screw I, said screw working through the upper forward end ofthe upper arm as most clearly shown and bearing upon the top of thehanger G. A rod K passes longitudinally through this hanger and isthreaded at its rear end as shown at K and engages the hanger F in whichthe rear end of the shaft E is journaled and by turning this shaft K bymeans of a suitable wrench, the shaft E can be shifted longitudinally soas to change the position of the roll E arranged upon the end E of saidshaft. The roll E together with the roll C are fastened upon the ends ofthe shafts E and C, respectively, in the usual or any approved manner. Acollar K is fastened upon the rod K, just to the rear of the hanger Gand the forward end is formed in a shoulder K and squared end K so thatby turning the said rod to either the right or to the left the shaft Ewill be moved in or out inasmuch asthe' hanger G is moved in or out andthe shaft E while turning freely within this hanger is fixed therein sofar as longitudinal movement is concerned. A gage rod L is fastened atits rear end in a suitable boss L and eX- tends parallel with the upperarm just above the lower edge thereof and this gage rod preferablyextends to the forward end of the machine and is adapted to carry thegage M and guide N, the gage M serving to act as a stop for the materialfed between the rolls and the guide N can be used as a guide or markerin shaping the bead or mold. The gage M and guide N, it will, of coursebe understood, are secured by means of suitable set screws after havingonce been adjusted. The casing is formed with an enlargement A at theupper end, in which is fixed a shaft 0, upon which is mounted a groovedpulley O, which is fast with the gear 0 mounted also upon the shaft 0and which meshes with the large gear D, so that when the pulley O isdriven the small gear or pinion 0 will transmit the power to the largegear D, which in turn rotates the lower shaft C and by means of thegears D and E the upper shaft E is caused to move in unison with thelower shaft C and in this way, the rolls E and C are driven in oppositedirections. By means of the hand nut and screw I, and the adjusting rodK, the relative positions of the said rolls can be regulated or gagedwith absolute accuracy.

In order to provide for the steady running of the machine, I preferablyemploy a friction brake P, carried by the arm P, which also carries abelt tightening pulley P at its upper end. The arm P is in the form ofan elbow lever pivoted at P at the upper end of the gear casing, theopposite end of said arm working in a guide I and adapted to receive apull rod or chain, which is preferably connected with the foot lever sothat by rocking the arm P, the belt the rocking movement of the arm Pbeing sufficient to release the brake shoe P, which is provided with anarm P to which is connected the coil spring P so that the momentpressure is relieved from the foot lever, this spring I will act tothrow down the arm P bringing the brake shoe P into contact with thepulley and at the same time, the arm P is shifted so as to carry thepulley P away from the belt thereby stopping the machine.

By means of a machine constructed as herein shown and described I amable to form beading or molding upon sheet metal metal with a perfectlysmooth edge and by means of folders arranged upon the ends of the shaftscan fold in the wire used around the edges of mud guards, fenders and soforth.

\Vhile I have shown and described my invention as a power machine, itwill of course be understood that the same broad principle can beutilized for a hand machine, the

power being applied to the small gear by means of a suitable crank.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is I 1. In a machine of the kind described,the combination with the horizontal shafts suitably mounted and driven,a pivoted hanger Fin which the rear end of the upper shaft is journaled,a spring supported hanger in .which the forward end of said shaft isjournaled, a hand wheel and screw adapted to bear upon said springsupported hanger and a rod working through the spring supported hangerand having a threaded end working in the pivoted hanger, the upper shaftand rod having collars upon opposite sides of the forward hanger wherebythe turning of the rod will move the hanger and upper shaftlongitudinally.

will be tightened. and the pulley O driven,

combination with a casing, of a lower shaft 2. In a machine of the kinddescribed, the

arranged therein, a hanger pivoted in the casing, a spring supportedhanger arranged "in the caslng' adjacent the forward end thereof, anupper shaft journaled in said pivoted and spring supported hangers,adjustable means for maintaining the spring supported hanger in positlontogether with means carried by the spring supported and pivoted hangersfor ad]ust1ng sald spring supported hanger and upper shaftlongitudinally and means for rotating said shafts.
